HCD-M10 SECTION 1
SERVICING NOTE
This appliance is classified as a CLASS 1 LASER product. The
CLASS 1 LASER PRODUCT MARKING is located on the rear
exterior.
Laser component in this product is capable
of emitting radiation exceeding the limit for
Class 1.
CAUTION
Use of controls or adjustments or performance of procedures
otherthan thosespecified hereinmay result in hazardous radiation
exposure.
Notes on chip component replacement
•Never reuse a disconnected chip component.
•Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Note for SpeakerTerminals
The negative speaker outputs are not grounded bevause of the
balanced transformerless circuit.
(If connecting them to ground, or each other, the circuit is broken)
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
break-down because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.
FOR CD
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pick-
up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
FOR MD
NOTES ON LASER DIODE EMISSION CHECK
Never look into the laser diode emission from right above when
checking it for adjustment. It is feared that you will lose your sight.
This caution
label is
located inside
the unit.

CHECKS PRIORTO PARTS REPLACEMENT AND ADJUSTMENTS IN MD
Before performing repairs, perform the following checks to determine the faulty locations up to a certain extent.
Details of the procedures are described in “Section 5 Electrical Adjustments”.
Note:
The criteria for determination above is intended merely to determine if satisfactory or not, and does not serve as the specified value for adjustments.
When performing adjustments, use the specified values for adjustments.
• 0.9 mW power
Specified value : 0.80 to 0.96 mW
• 7.0 mW power
Specified value : 6.8 to 7.2 mW
Iop (at 7.0mW)
• Labeled on the optical pick-up
Iop value ±10mA
• Unsatisfactory if displayed as “NG : XXXX”NG
(XXXX are arbitrary numbers)
• Unsatisfactory if displayed as “T=@@ (##) [NG]”
NG
(@@, ## are both arbitrary numbers)

Auto check
(6-4 : See page 34)
Temperature
compensation
offset check
(6-1 : See page 33)
Criteria for Determination
(Unsatisfactory if specified value is not satisfied) • Clean the optical pick-up
• Adjust again
• Replace the optical pick-up
• Replace the optical pick-up
• Replace the optical pick-up
• Check for disconnection of the circuits around
D101 (BD board)
• Check the signals around IC101, IC151, CN102,
CN103 (BD board)
Measure if unsatisfactory

JIG FOR CHECKING BD (MD) BOARDWAVEFORM
The special jig (J-2501-196-A) is useful for checking the waveform of the BD (MD) board. The names of terminals and the checking items
to be performed are shown as follows.
GND : Ground
I+3V : For measuring Iop (Check the deterioration of the optical pick-up laser)
Iop : For measuring Iop (Check the deterioration of the optical pick-up laser)
